sort of...
A friend of mine was the photographer for the high school newspaper and year book. He had a Pentax Super Program. A couple of years after high school, he and my brother moved across country, so they sold off anything they could to raise $$ for the trip. That was probably 1990.
I bought the whole camera kit. It included an Auto flash, a Vivitar 28/2 and an SMC-A50/1.4 in a huge camera bag.
When my son was born in 1998 I got it out to improve the pictures we were getting of our little smoochy. When he got to about 18months, I couldn't focus fast enough anymore so I bought a ZX-5n with the "good" zoom, FA28-70/4. The lens now has lens element separation
I started getting film processed and scanned so I could play with the shots on the computer instead of just getting 4x6's to throw in a drawer somewhere. I eagerly followed the digital camera explosion, got a canon point and shoot 5mp for my wife.
A couple of months before my daughter was born 2007 my wife told me to stop analyzing and just buy a new camera. So I had to pick... used DS or K100Dkit?
I bought the K100D February 2007 mostly for SR. That was the feature that would actually improve my pictures. Loved the ability to use my old lenses.. of course none of the three lenses I previously owned has been on this new camera much!
I prefer the M28/3.5 over the Vivitar28/2, the FA28-70/4 is broken, and I loaned the A50/1.4 to a friend because I have the FA50/1.4.
I have added a bunch of cheap M glass (M28/3.5, M35/2.8, M100/4Macro(1:2), M135/3.5, M200/4) only the macro and a new Zenitar 16/2.8 were over $100. So the lenses cost around $600 total. So I do appreciate the compatibility, but not to use my old lenses.. to use other peoples old lenses!!
